在本组30例患者中16例为先天性主动脉二瓣化畸形，23例主动脉瘤壁病理结果显示主动脉壁弹力纤维断裂（6例）、稀少（1例）和中、重度黏液性变（16例）。

Background— Bicuspid aortic valve is a heritable condition that has been linked by an unknown mechanism to a predisposition for ascending aortic aneurysm.

Methods morphology ,opening,closing and hemodynamicon short axes section of large arteries and on long axessection of aorta were observed.results thickening,calcification ,hemodynamic,morphologic changes of the aortic wall were exacerated with increased age of patients.conclusion cdfi is of great valve in diagnosing bicuspid aortic valve.

重点通过大动脉短轴及主动脉长轴等切面观察二叶式主动脉瓣的形态、回声、启闭及血流动力学情况。结果：随着年龄的增长，瓣膜增厚、钙化、血液动力学、心脏形态学改变逐渐加重。结论：彩超对先天性二叶式主动脉瓣畸形及病变的诊断具有重要意义。

The anatomic subtype included type A 18 (85.7%),type B 3 (14.3%),and no type C in the records.All cases were associated with large PDA and VSD,some also with ASD,bicuspid or unicuspid aortic valve,and subvalvular aortic stenosis.

所有病例均合并粗大动脉导管未闭及大型室间隔缺损，其它伴发畸形包括继发孔房间隔缺损、主动脉瓣单瓣或两瓣畸形、主动脉瓣下狭窄。

Thus, many individuals with bicuspid aortic valves develop clinically important aortic stenosis during late middle life sometime between the 5th and 6th decades.

所以，大部分二叶主动脉的个体在五、六十岁时出现严重的主动脉狭窄症状。

Methods Fifteen dogs were randomly divided into 3 groups. Group A acted as the control group without CPB; group B and group C were subjected to cardiopulmonary bypass and crossclamping the aorta for 90 min. MP or saline was injected intravenously before surgery. Plasma levels of IL-1β、TNF-α、IL-6、IL-8 and IL-10 were measured at the following time points: before MP or saline were administered, aortic declamping, 30 min and 90 min, after aortic declamping. Immediately after the animals was killed, pulmonary arterial rings were obtained and mounted in organ chamber for assessment of endothelial function with endothelium-dependent or non-endothelium-dependent studies.

健康家犬15只，随机分为3组，A组：不进行CPB，作为非体外对照组；B组：麻醉后注射生理盐水10mL，常规全麻和CPB，主动脉阻断90min；C组：麻醉后静脉给予甲泼尼龙5mg/kg，其余处理同B组。B、C组分别在手术前及主动脉开放前、开放后30min和90min 4个时间点采动脉血，放免法测定血浆白介素－1β(IL-1β)、肿瘤坏死因子－α、白介素－6(IL-6)、白介素－8(IL-8)和白介素－10(IL-10)水平；手术结束时，A、B、C 3组均取右肺动脉段，固定于张力传感器，测定血管环内皮依赖性和非内皮依赖性扩张能力的变化。

Among them, 20 patients were candidates of valve replacement and 18 PDA and pericarditis had their blood samples taken before operation,and 1,2,24 and 48 hours after closure of thorax for measurement of concentrations of CK、CK-MB and TnT,together with ECG recording. Results Of the 60 patients, concentrations of cTnT before operation were normal; 2 hours after aortic unclamping, the correlation coefficient between cTnT and aortic clamping was r = 0.873( P＜0.01), the regression analysis showed Y = 0. 019X-0. 026. Of the 20 patients, ECG showed the myocardium was ischemic; CK、CK-MB and cTnT all rose significantly, reaching the peak after closure of thorax. Of the 18 patients, the ECG and cTnT before operation and after closure of thorax were normal; except 2 patients with pericarditis.

结果 60例瓣膜手术患者术前cTnT均在正常值范围内，主动脉开放后2 h时，阻断时间和cTnT的相关系数为r=0.875(P＜0.01)，回归方程为Y=0.019X-0.026；其中20例瓣膜手术患者心脏经过阻断后，心电图有缺血性改变，周围血液中的CK、CK-MB和cTnT均有明显升高，分别在关胸后2 h达到高峰，数值分别为术前的12.6、9.2和257倍；18例行动脉导管结扎和心包剥脱术的患者术前和关胸后的心电图和血液中的cTnT均正常，CK和CK-MB除2例心包炎患者关胸后出现明显变化外，余均未见改变。

These changes were abolished in 2K1C rats treated with captopril. L-arginine partially reversed the change of aortic contractibility of 2K1C rats, and elevated aortic cGMP content.
